To all whom/t may concern:

Be it known that I, JOSEF PEJCHAR, a citizen of the United States, and resident of; the borough of Brooklyn, in the `county of Kings, city and State of New York, have:

invented certain new and usefulA Improvements in Tweezers,of .which the following' l thereby, as by` making said member with a is a specification.

My invention relates to tweezers, particularlyof the kind used by jewelers forthe purpose of pickingvup and bringing to thedesired place, precious stones or.l the .like.` The chief object of my present invention 1s to arrange a gage or scale adjacent` t0. the

seizing or holding portion of the instrument,

so that the scale and the stone or other article held by the tweezers may be readily seen at one glance, and the size of such article ascertained without compelling-,the .user to divert his eye from such stone. Another, object of my invention is to combine with tlie tweezers, cutting and scraping, or implement-holding devices which will adapt the instrument to different uses, as will be fully set forth hereinafter.

Reference is to be had to the accompany-v ing drawings, in which Figure 1 is a side elevation of tweezers embodying my improvements; Fig. 2 is' a front view thereof, showing the tweezers open; and Fig. 3 is a front view showing the tweezers closed upon a stone or like article, a portion of the instrument being shown in section in this View. It will be understood that the drawings illustrate only an example of my invention, and that various modifications may be made without departing from the nature of my invention as set forth in the appended claims.

In the example illustrated, A, A are two spaced and diverging members connected at one end, as indicated at a, but free to move together or apart in their main portions and particularly at their other ends. The separated portions of these members tend to spread apart, for which purpose they are made elastic, but preferably the extreme portions b, which form the holding portions of said members, are made rigid, for a purpose to be explained below. When closed upon the article to be grasped (such as a precious stone S), the inner faces of the holding portions b are parallel to each other, or nearly so. With one of the members, say A', is connected rigidly, preferably at the rigid holding portion b thereof, a transversely-extending measuring member or gage. B having a suitable graduation or. Y

scale B-, preferably along that edge which isjnearestto the free ends of the` holding portions j This gage .may be made integral withthe member carrying'j it.- `The freeend` of -the gage,V B is in'contactjwithl the other member f (A), and is preferably ,guidedi i dovetailgrooveA and giving the gage B a corresponding (say, triangular) cross sectiOn, see, Fig. l. Itwill beobservedthat the gage arm `B -isflat and extends from theL 'front face of the `member A-, also that the front face of said arm B is exposed where 1t crosses the arm A, so yas to be readily vislble...= For this purposethe guide .A has projections which extend in front of the respective edges of the gage arm and prevent .its forward movementwhilefallowing it Yto slide transversely, and these projections are therewith, the two circular edges of whichsleeve may be sharpened, and this sleeve may be, used as'a scraper or cutter, say for the purpose of making a groove in a piece of chalk, or for holding a lead-pencil or other article which may be fitted into the socket formed by the sleeve C. As shown, the other member, A', projects beyond the member A and the sleeve C at the end thereof, and this projecting end of the member A may be made with one or two knife edges, say a straight longitudinal edge a and an oblique or slanting edge a, converging toward the extremity of the member A.

When used as tweezers, the instrument is grasped in the usual way, with the connected portion a; toward the persons wrist, and the two members A, A pressed toward each other and against the stone S or other article (Fig. 3), by the yusers thumb and forenger. Inasmuch as the gage B is adjacent to the holding portions it will be obvious that the person using the instrument will be able, at one glance, to keep the stone or other article in View (so as to make sure it is being held properly) and at the `same time ascertain, by means o`f"'t'li'"sc"al`e` B 'of' the gage B, the dimensions of such article.

If the scale were at such a distance from the holding portion b as tocompel., fthe-user to shift his eye `from 4one to the other, this would be open to the seriol'isiobjeetefthatfis when looking at the scale, he would, never be quite' "sure that 'the holding `portio1is of they instritment'` Awere in; proper' c'ntact- Wi-tl the article to be measured". It preferable to'have the"'holding-portions Zi rigid, and aprivvv proxiinatelfyi paralleli to 'achiotlieig i Vorder that the indications of' the scale may/not be7` made inaccurateA by any flexing oit th points offc'o'n'tact Witlrlthe storiey S'I orfoth'er articld-and also iii-order that Ytlie'i'ndiean at one end?, 'and novabletoftyard .and from eachother atftheirotlier ends", said'- lastcomprising' two?y 'mernbe'r's'i'-` named ends being rigid, and a flat gage arm connected.
